A flexible bearing cage includes a base ring comprising a plurality of mount sections arranged along a circular path and a plurality of compressible fold sections. One of the compressible fold sections is located between each adjacent pair of the mount sections, and a finger projects axially from each of the plurality of mount sections. Each of the fingers has a partially spherical concave surface configured such that the finger projecting from a first mount section on one side of a first one of the compressible fold sections and the finger projecting from a second mount section on a second side of the first one of the compressible fold sections define a partially spherical cavity configured to receive and retain a respective rolling body.
